Senior Full-stack Developer Roundtable

About the role

We are looking for a highly skilled Senior Full-Stack Developer to join our tech team.

As collaborative building is at the core of how we operate - not just within the engineering team but across all departments. We are developing a platform that offers an incredible opportunity to co-invest in the Private Equity sector. To achieve our vision, we need to establish both a premium brand and platform.

As our tech team continues to scale, you’ll wear many hats. Your responsibilities will include:

• Collaborating closely with the team on product strategy, assessing the effort required for various features, and making key technical decisions

• Supporting the overall decision-making process and the company’s sustained growth

• Developing, deploying, and maintaining new features

• Conducting code reviews and facilitating knowledge sharing within the team

What you’ll work on

• Cap table engine: Build systems that track ownership across thousands of investors with cent-level precision

• Multi-country compliance: Implement investor qualification rules and regulatory workflows across jurisdictions

• Multi-asset platform: Extend the platform to support diverse asset classes and investment structures

• Financial operations: Design robust workflows for complex financial transactions and fund operations

• Real-time dashboards: Create high-performance investor platform with live portfolio valuations

• Document automation: Generate legal documents (subscription agreements, shareholder reports) from dynamic templates

• Security: Protect sensitive financial data with robust authentication, authorization, and encryption

Technical challenges

We handle sensitive financial data, which presents us with unique challenges:

Precision at scale: Our engines compute fractional ownership across thousands of investors. Rounding errors must cascade correctly - we can’t lose or create cents.

Complex financial state machines: Financial operations involve coordinated updates across multiple entities and ledger entries. State transitions must be atomic and auditable.

Multi-jurisdiction compliance: Different countries have different regulatory requirements. The system must enforce these rules programmatically while remaining flexible.

Historical reconstruction: Auditors need to see data at any point in time. Our architecture supports point-in-time queries tied to specific operations.

Domain complexity: We model sophisticated financial instruments and multi-currency valuations all with type safety.
